I'm looking for Serial Cable pinouts for my UPS
The UPS Model is (Eaton) BestPower Patriot 425.
The cable needed is INT51 (INT-0051) compatible with:
Best Power UPS:
Unity one and three phase
CheckUPS II Basic
There is some information in the manual:
Pin 1 RS232 Level Shutdown: +12 VDC signal held for 5 seconds on this pin shuts Patriot
down 120 seconds later. The UPS restarts after 15 seconds when utility power returns.
Pin 2 Unused.
Pin 3 Normally Open On-Battery Contact: A normally open contact that closes 15 seconds
(pulls to Common) after the UPS switches to battery power.
Pin 4 Common: The signal ground for all signal pins.
Pin 5 Normally Open Low-Battery-Alarm Contact: A normally open contact that closes
(pulls to Common) during a Low Battery Alarm.
Pin 6 Normally Closed Low-Battery-Alarm Contact: A normally closed contact that opens
(releases from Common) during a Low Battery Alarm. This tells some shutdown
software when to start a computer shutdown.
Pin 7 Unused.
Pin 8 Normally Closed On-Battery Contact: A normally closed contact that opens
15 seconds (releases from Common) after the UPS switches to battery power.
Pin 9 Unused.
Contacts consist of open collector circuits capable of switching up to +30 VDC, 6 mA resistive
But I don't know how to connect it to the PC...
The NUT (/www.networkupstools.org) uses genericups upstype=6 to comunicate with this UPS.
